The Corbeau bracket (double locker) has spots on the side to mount the lap belts and I welded a sub bar to the bracket under the seat. Just some square tubing that put the sub strap at the right angle. The right way is to apparently drill through the floor and use some reinforcement plates, but that seems kinda sketchy in comparison to my setup as far as strength goes. The shoulder harnesses are obviously hung from the harness bar.

I'll take some photos when I'm home and have sufficient light in the garage.
